NEET2018PhysicsCurrent ElectricityActual
Find current (i) in circuit shown in figure.
Options
- A0.5 A
- B0.2 A
- C1 A
- D2 A
Correct answer
A. 0.5 A
Step-by-step solution
Above circuit is satisfied, the Wheatstone bridge condition, so no current is flow in the branch BC and it behaves like an open circuit. So, circuit becomes as shown below Now, in the above circuit aligned & R _ ABD =5+10=15 & R _ ACD =10+20=30 aligned Resistance, R _ ABD and R _ ACD in parallel, so aligned R _ net & = 15 30 30+15 = 450 45 =10 i & = E R _ net = 5 10 & =0.5 ~A aligned
